Portable hygrometer MICHELL INSTRUMENTS
MDM300

The MDM300 is a high-speed dew point portable hygrometer which uses Michell’s ceramic impedance sensor and state-of-the-art thin and thick film techniques. Operation of the sensor depends upon the adsorption of water vapour into a porous, non-conducting “sandwich” between two conductive layers built on top of a base ceramic substrate. The MDM300 provides the fastest spot check measurement of dew point or moisture content in a small portable instrument and is packed with features and intelligent engineering.

The user-friendly MDM300 offers an extremely fast response speed and an accurate and stable measurement. The hygrometer has data-logging and built in sampling components as standard and a range of optional accessories are available such as a stand-alone sampling system and a professional carry case.

The MDM300 uses the latest Bluetooth wireless technology to offer a quick and easy assembly and downloading process. With a choice of four different sampling arrangements (from fixed orifices for low pressure to high quality configurable sampling systems for high pressure), the MDM300 offers a cost effective and easily portable service to the user. The MDM300 is able to connect to external sensors to measure dew-point, temperature and pressure and also to re-calibrate other Michell Instruments such as the Easidew Transmitter. The original design and long battery life makes a perfect hygrometer for laboratory or portable use.
